I just bought a 2002 with 106K miles, and replaced both. I have owned a number of FWD chrysler products. It seemed like there were a whole lot of issues with 82-85 wheel bearings, and went away. We owned two neons that ran 168, and 190K miles without having to replace them. I am suprised by the responses here. They may be using China crap bearings, rather than SKF or some other reputable brand.

Fortunately, I built a wheel bearing puller for the old k-car stuff and works fine on the PT. I can do it myself without wrecking the alignment. You just have to disconnect the lower ball joint, pull out the axle. I can make a posting if someone is interested.
